  • Patent number: 11401187
    Abstract: Provided are: a water treatment method that includes at least a denitrification step for denitrifying water to be treated with a denitrifying bacterium in the presence of a hydrogen donor, wherein the denitrification activity of the denitrifying bacterium can be maintained at a high level and thus the treatment speed can be increased; and a water treatment apparatus. The water treatment method includes at least a denitrification step for passing water to be treated through a biological treatment tank and denitrifying the same with a heterotrophic denitrifying bacterium in the presence of a hydrogen donor, wherein: molybdenum is added to the water to be treated to give a concentration of 0.01-1.0 mgMo/gN; a carrier is added to the biological treatment tank; and the nitrogen load to the carrier is controlled to 1.6 kgN/(m3-carrier·d) or greater.

  • Patent number: 10975206
    Abstract: A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamine acid is dissolved in a polar solvent. An inorganic salt is added to the solution, and a mole ratio of moisture to the inorganic salt in the solution is 2.5×m×n or less, where m represents the number of cations forming the inorganic salt and n represents a charge number of the cation. A production method of the present invention is a method for producing the above solution, including: changing at, least one of a moisture content and a content of the inorganic salt in the solution to adjust a viscosity of the solution. Thus, the present invention provides a polar solvent solution whose viscosity can be easily adjusted to a desired value and thus enables stable spinning and casting when used as dopes for spinning, film, etc., and methods for producing the same.

  • Publication number: 20200131671
    Abstract: A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamine acid is dissolved in a polar solvent. The solution has a moisture content of less than 5 mass % based on 100 mass % of the solution. A method for producing a polar solvent solution of the present invention includes changing a moisture content of the solution to adjust the viscosity of the solution. Further, another method for producing a polar solvent solution includes reducing a moisture content of the solution to increase the viscosity of the solution. Thus, the present invention provides a polar solvent solution that enables stable spinning and casting without lowering its viscosity when used as dopes for spinning, film, etc., and methods for producing the same.

  • Patent number: 9236430
    Abstract: The deposition rate of a porous insulation film is increased, and the film strength of the porous insulation film is improved. Two or more organic siloxane raw materials each having a cyclic SiO structure as a main skeleton thereof, and having mutually different structures, are vaporized, and transported with a carrier gas to a reactor (chamber), and an oxidant gas including an oxygen atom is added thereto. Thus, a porous insulation film is formed by a plasma CVD (Chemical Vapor Deposition) method or a plasma polymerization method in the reactor (chamber). In the step, the ratio of the flow rate of the added oxidant gas to the flow rate of the carrier gas is more than 0 and 0.08 or less.

  • Patent number: 8998734
    Abstract: A thread forming tap has a full thread portion and a leading portion contiguous with the full thread portion and reducing in diameter toward its tip. The full thread and leading portions are provided with external thread on which lobes and recesses are alternately formed. When ? represents an angle around a tool center line toward a thread forming side, the shape of the lobe varies along a quadratic curve relative to angle ? so that relief amount increases toward inflection point angle ?. However, in a rough plastic deformation section where angle ? is greater than inflection point angle ? and exceeds the working region, the shape varies along an Archimedean curve with clearance angle ?1 so that the relief amount increases linearly relative to angle ?, and a margin section is substantially zero or within a range where angle ? is less than or equal to 1°.

  • Patent number: 8828178
    Abstract: A sealing device which comprises a slinger fixedly fitted to the rotary side member, a core member fixedly fitted to the stationary side member, and an elastic sealing member fixed to the core member and having a seal lip which elastically and slidably contacts the slinger. The slinger comprises a fitting cylindrical portion to be fitted into the rotary side member, a brim portion extending its radial direction at one end of its outside relative to a sealed portion of the fitting cylindrical portion, and a rotary side fixing member fixed to the brim portion. Further, the slinger is made in such a manner that an adhesive layer is formed on its whole surface including a contacting side surface where the seal lip contacts by applying adhesive agent thereon, then the fixing member is integrally fixed thereto, thereafter the adhesive layer is partially removed only in the contacting side surface.
